Be sure to have the Periodic Table of elements handy:
Number of Protons = Atomic Number Number of Neutrons = Mass Number - Atomic Number (Mass number minus atomic number)

What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
How many protons neutrons electrons in atom of fluorine?
An atom of Fluorine has the atomic number 9 and the mass number 19 (rounded up). This means it has 9 electrons, 9 protons and (19-9) 10 neutrons. The proton and electron count are taken from the atomic number. The mass number - the atomic number gives the number of neutrons.
N atom has 7 protons and a mass number of 14 What is the number of neutrons in an atom of N?
Unless N is a isotope it will have the same amount of neutrons as protons
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
40, the sum of the protons and neutrons.
What is the total count of the neutrons an protons in an atom?
The sum is called mass number.
What are the relationship between protons and neutrons in a atom?
The atomic number corresponds to the number of protons in the nucleus of an atom. It also corresponds to the number of electrons in a neutral atom. A neutral atom, you'll recall, is one where the number of electrons equals the number of protons in the nucleus of an atom. We remember that atoms often "loan out" or "borrow" electrons, so the electron count will not always equal the proton count.
The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What particles make up the mass of an atom?
The number of protons
The number of protons and neutrons in an atom?
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
How do you determine the number of protons in an atom of aluminum27?
There are 13 protons in an atom of aluminum, regardless of the isotope. If it didn't have 13 protons, it wouldn't be aluminum, it would be something else. There are 14 neutrons in an atom of aluminum 27, its only stable isotope.See the Related Questions for how to count the number of protons, neutrons and electrons in any atom of any element.
